this has been on the PTR for about a week, duders. frostbolt with no cooldowns popped crits for ~77k vs. s13 geared players. with everything popped (damage trinket, incanter's), it crits for 110k+ haste geared, even more with mastery. I crit a moonkin last night for more than 124k
The Freeze nerf reduces your FoF procs a fair amount, so your instant cast damage is less numerous. We do too much damage on PTR though if we're allowed to cast.
Get Incanter's popped
Dmg trinket+icy veins
Pom, Alter Time
Lance Brain Freeze Lance
100-0 every single time
I wanna live in your dreamworld full of ponys and candy where a mage can chaincast frostbolt in arena
